Fig. 5. Tissue distribution of SkUT using high-stringency northern analysis. Membranes were probed using ³²P-labelled random-primed SkUT cDNA probe and hybridized at 65°C. Each lane contained 10 µg of total RNA. K, kidney; L, liver; G, gill; B, brain; H, heart; I, intestine; M, muscle. The positions of kb markers are shown.
